6 Claims.

The present invention relates to new and useful improvements in jacksand more particularly to vehicle bumper 'jacks.

An important object of the invention is to provide a safe, non-slippingclamp or rest carried by the jack for engaging a vehicle bumper whilethe vehicle is being jacked.

Another object is to provide a bumper rest which may be used on a jackpost of various types of jacks, such as screw, friction, hydraulic,ratchet or other well known types of jacks.

A further object is to provide a device of this character of simple andpractical construction, which is efficient and reliable in operation,relatively inexpensive to manufacture, and otherwise well adapted forthe purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawing forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view;

Figure 2 is a top plan view;

Figure 3 is a fragmentary vertical sectional view taken on a line 3-3 ofFigure 1;

Figure 4 is a transverse sectional view taken on a line 6-4 of Figure 1;and

Figure 5 is a fragmentary rear elevational view taken at a pointindicated by lines 55 of Figure 1.

Referring to the drawing in detail wherein for the purpose ofillustration I have disclosed a preferred embodiment of my. invention,the numeral 5 designates an elongated slide of U-shape in cross sectionand positioned vertically on a jack post 6 which may be of a screw type,as illustrated in Figure l, or which may form a part of other types ofjacks, such as friction, hydraulic or ratchet jacks.

A rocker 1 includes a forwardly projecting inverted channel arm 8 whoseflanges project rearwardly at opposite sides of the screw to provide ayoke 9 whose sides are pivoted intermediate their ends to upwardlyextending ears Ill rising from the sides of slide 5 by rivets II. Therear ends of yoke 9 are pivoted to a lug l2 by a pin I3, the lugprojecting at the rear edge of a nut or carrier ll threaded on thescrew.

The lower edges of channeled arm 8 are formed with aligned notches l5 toreceive the upper edge 2 inclined channeled arm l8 having notches I! inits upper edge for receiving the lower edge of the bumper, and a pair ofrearwardly projecting spaced parallel arms positioned at opposite sidesof the slide 5, the arms 20 being formed as a continuation of theflanges of arm l8 and are likewise inclined upwardly.

A pin 2| connects the rear ends of arms 20 behind the slide 5 and isselectively seated in vertically spaced notches 22 formed in the rearlower edge of the slide to vertically adjust the bumper rest I! on theslide.

A stop 23 projects rearwardly from the lower edge of the slide toprevent removal of the bumper rest therefrom.

In the operation of the device, the screw is supported at its lower endin a base 24 and the slide 5 is supported on the jack post by the nut l4and rocker I. The rest I7 is adjusted on the slide to engage the loweredge of the bumper I 6 and with the rocker l engaging the upper edge ofthe bumper as shown in Figure 1.

The jack post is rotated in a direction to move nut l4 upwardly whichthus raises slide 5, rocker l and rest I! between which the bumper issecured to thus jack a vehicle to which the bumper is attached.

The initial upward movement of nut l4 raises the rear end of yoke 9 bypin it to pivot the rocker l on rivets H and thus force arms 8downwardly into tight clamping engagement with the bumper to hold thebumper on the arm ID of bumper seat H.

In view of the foregoing description taken in conjunction with theaccompanying drawing it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A jack of the class described comprising in combination with a jackpost of a pair of coacting vehicle bumper clamping members, and meanssupporting the clamping members for vertical adjustment on the post, oneof said clamping members being pivoted to said supporting means andmovable into and out of clamping engagement with the bumper by thevertical adjustment of.

3. A jack of the class described comprising in combination with a jackpost of a vertically adiustable slide carried by the post, a verticallyadjustable vehicle bumper rest carried by the slide, and a vehiclebumper clamping arm pivoted on the slide and coasting with the rest toclamp a bumper thereon.

4. A jack of the class described comprising in combination with a jackpost of a vertically ad- Justable slide carried by the post, avertically carrier for actuation by a vertical movement of the carrier,and a vehicle bumper rest carried by the slide, said rocker coactingwith the rest to clamp a bumper thereon.

6. A lack of the class described comprising in combination with a jackpost oi a slide carried by the post, a carrier vertically adjustable onthe post and connected to the slide, a rocker pivoted to the upper endof the slide and connected to the carrier for actuation by a verticalmovement of the carrier, and a vehicle bumper rest carried by the slide,said rocker coacting with the rest to clamp a bumper thereon, and saidrest being vertically adjustable on the slide.
